Love them!
I just ordered three more swaddles in medium. I've used them since my baby was approx 2 weeks old and I honestly love them. In winter they kept him warm, even his hands, and they stop the startle reflex from waking him. He knows when I pop him in his Love to Dreams that it's time for sleep, I use them day and night. I bought a transitional one for when he's rolling and won't use them any more and I dread the day he's not in them any more!
